Headlamp cleaning system
If the "Wipe with washer fluid" function is
operated five times (Y page 132) while the
lights are on and the engine is running, the
headlamps are cleaned automatically. When
you switch off the ignition, the automatic
headlamp cleaning system is reset and count-
ing is resumed from 0. Intelligent Light System
General notes The Intelligent Light System is a system that
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions.
It offers advanced functions for improved illu-
mination of the road surface, e.g. depending
on the vehicle speed or weather conditions.
The system includes the active light function, cornering light function, motorway mode and
extended range foglamps. The system is only active when it is dark.
You can activate or deactivate the "IntelligentLight System" using the on-board computer
(Y page 247).
Active light function The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Active: when the lights are switched on. Cornering light function
The cornering light function improves the illu-
mination of the road over a wide angle in the direction you are turning, enabling better vis-
ibility in tight bends, for example. The corner- ing light function can only be activated when
the dipped-beam headlamps are switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the
steering wheel
R if you are driving at speeds between
40 km/h and 70 km/h and turn the steer-
ing wheel
Not active: if you are driving at speeds above
70 km/h or switch off the turn signal or turn
the steering wheel to the straight-ahead posi- tion
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.
